Touch screen panel

摘要

A touch screen panel is disclosed. In one aspect, the touch screen panel includes a substrate divided into a display area and a non-display area positioned outside the display area, sensing lines in the display area and wiring lines in the non-display area. Each wiring line is connected to two or more sensing lines. The switching units are connected to the sensing lines and the wiring lines so as to selectively connect one of each of the sensing lines to each of the wiring lines.

1. A touch screen panel, comprising:
a substrate divided into a display area and a non-display area outside the display area; a plurality of wiring lines in the non-display area, the wiring lines comprising a first group of wiring lines on a first side of the non-display area and a second group of wiring lines on a second side of the non-display area opposing to the first side; a plurality of sensing lines in the display area, wherein for each wiring line, at least two sensing lines are in the display area; a plurality of switching units between the sensing lines and the wiring lines to selectively connect one of the at least two sensing lines for each wiring line to each wiring line, the switching units comprising a first switching unit on the first side and a second switching unit on the second side, wherein each switching unit comprises: a first transistor connected between a first sensing line and a first wiring line; and a second transistor connected between a second sensing line that is adjacent to the first sensing line and the first wiring line, the first sensing line being an odd sensing line and the second sensing line being an even sensing line; and a controller configured to output sensing signals for driving the sensing lines and an output signal for controlling the switching units, wherein the first switching unit is connected to the first group and the second switching unit is connected to the second group, the first and second switching units being connected to different sensing lines to each other, and wherein the controller sequentially: transmits one or more sensing signals having predetermined voltage levels to the wiring lines, and transmits a first gate signal to the first transistor, and transmits a second gate signal obtained by inverting the first gate signal to the second transistor.
